hey honey!!!
it sounds like you are a bit down....
everyone has their own threshold of patience.. you need to decide for yourself.. but there does come a point when you have to do what is best for you.. you cannot keep dweeling on things and let them continue hurting you.. you are too good a person and young and things will always get better!!! take it from a season vet..
miss you!!! love, dani

It depends on the situation, but at some point in time, it's no longer "giving up", but rather, "moving on"... and that's a perfectly healthy thing to do. It's that point when hope has finally died and the potential benefits no longer outweigh the pains of staying where you are... Like Dannette said, that point is different for different people and different situations.... sometimes it's good to step back and take a look and if you don't like what you see, it's time to change something until you do

Giving up is never really an option. I don't think I've ever really 'given up' on anything. Sure, things get set aside, maybe delayed, and you wait until the right time to dust it off comes around. When it does, you'll know. Don't give up, just think bout it realistically. Hell, some stuff has been on the shelf for 6 or 7 years. It's just not time yet.

The best time to give up is before you have started. However, having failed that first part, you give up when you no longer see any benefits. Theoretically it should work, since why would you do something if nothing were to come of it?
